  1. 11. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Vikramjeet Das; [2023]
    Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

  3. 12. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Arvid Söderlund; [2023]
    Keywords : Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

    Abstract : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

  4. 13. Revival structure of the residual entanglement in a three-qubit system

    University essay from

    Author : Carl Agelii; Rasmus Andersson; William Bakke Lindblom; [2023]
    Keywords : qubit; tripartite entanglement; residual entanglement; antisymmetric exchange; Quantum Heisenberg model;

    Abstract : The quantum mechanical phenomenon of entanglement plays a key role in areas such as quantum computing and quantum information. Entangled half spin particles, often called qubits, are used to realize quantum based logic which means that studying systems of qubits and their properties is of vital importance to the development of the fields.

  5. 14. Full Duplex for Joint Communication and Sensing in 6G.

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Soumya Jandhyala; [2023]
    Keywords : ;

    Abstract : Background: 6G mobile communication is one of the fastest-growing fields of technology. The present 5G mobile networks will not be adequate to meet society’s wireless connectivity demand in the near to mid-term future. A new generation of wireless mobile networks has to be developed to address this demand. READ MORE

  6. 15. Batteries charging into the future? Techno-economical analysis of BESS participation on the Swedish frequency regulation market using a mixed method approach

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Theodor Rosengren; [2023]
    Keywords : Battery Energy Storage Systems; Frequency Regulation; FCR-D; FFR; economic feasibility; Sweden; Technology and Engineering;

    Abstract : As the penetration of variable renewable energy is increasing, the demand for flexibility in the electrical grid is on the rise. One way in which flexibility is needed is to provide frequency regulation. If electricity consumption and production momentarily are unbalanced there needs to. READ MORE
